Lesson Plan 5 – TI-Nspire
INTC 5320
March 2, 2010
OBJECTIVE: 7-6.2 Evaluate Expressions. Students will be able to evaluate expressions and
variable expressions. Students will be able to use substitution to evaluate an algebraic
expression. Students will be able to determine the role of the coefficient and the constant term in
an expression. Students will be able to identify patterns and make generalizations based on
observations when values are substituted into an expression. Students will be able to use the
“Action/Consequence” abilities of the TI-Nspire system to observe how the values of an
expression change as different values are substituted.
ENDURING UNDERSTANDINGS: Students will understand that integers can be labeled on
a number line (either horizontal or vertical). Students will understand that the magnitude of
numbers affects the outcome of operations on them. Students will understand that the symbolic
language of algebra is used to communicate and generalize the patterns in mathematics.
Students will understand that patterns and relationships can be represented graphically,
numerically, symbolically, or verbally.
DO NOW: Selected Questions taken from Spiral Review, Open Ended Test Prep and Logical Thinking.
ACTIVITIES: Do Now, Review Homework, Notes and Examples. This lesson involves
substituting values for variables, and evaluating expressions. The emphasis is on helping students
understand that an expression and an equation are two distinctly different mathematical objects.
Students will slide a point attached to an arrow along a number line in the TI-Nspire system and
be asked to observe the changes that take place in the expression as the value of the variable
changes. As a result students will make conjectures about the connection between the values
being substituted in the expression and the outcomes. The lesson could lead to solving a linear
equation in one variable or be extended to generating a table of solutions for a linear equation in
two variables.
Vocabulary: Coefficient, Constant term, Linear equation Materials needed: SMART Board, TI-Nspire calculators and software
GUIDED PRACTICE: Teacher will first demonstrate use of the Action/Consequence slide in
the TI-Nsprire software and then the students will slide the tool and make observations regarding
the outcomes. Teacher will facilitate and guide this discussion.
INDEPENDENT PRACTICE: SEARCH Lesson 7-6.2 pages 272 and 273.
STANDARDS: Technology: 8.1 A-F, 8.2 A-G
Mathematics: 4.1 Numbers and Numerical Operations
4.3 Patterns and Algebra
4.5 Mathematical Processes
